Patented Dec. 1, 1908.

Application filed June 14, 1907.1Serial No. 378,969.

To all whom it may concern:

Be it known that I, PHILIP NEHLIG, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Gasstove, of which the following is aspecification.

My invention consists of a gas stove composed of a casing, an air flue,a burner and a diaphragm in said casing adapted to direct the productsof. combustion in a circuitous direction or course from the burneremployed to the discharge flue, thus obtaining an increased heatingaction of the products of combustion and consequently producing agreater volume of heat, the means employed being hereinafter described,and the novel features pointed out in the claims.

Figure 1 represents a vertical section of a gas stove embodying myinvention. Fig. 2 represents a horizontal section on line w-m, Fig. 1.Fig. 3 represents a horizontal section on line y-@ Fig. 1.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings :A designates the casing of the stove, and Bdesignates a flue, shown as tapered with the larger end uppermost,adapted to receive air which is to be heated, as will be hereinaftermore fully described, said flue being open at top and bottom, the air,in the present case, being admitted thereto by means of the branch orsupply pipe O, which is connected with the bottom of the flue.

The top of the casing A is closed by the wall D, and the bottom thereofis provided with the plate E, which is partly perforated, so as to admitair to the burner F within the casing A, said burner having connectedwith it the pipe Gr, whereby it may be supplied with gas for evidentpurposes.

l/Vithin the casing A below the exit flue H, is the horizontallyextending diaphragm J, which is of the form of the segment of a circleand has between its ends the passage K,whose position is at the frontportion of the stove, opposite to, or comparatively disposed to saidexit flue thus forming a communication between the upper and lowerportions of the interior of the casing, while the dia phragm cuts-offsuch communication, it being noticed that said diaphragm closely engagesthe walls of the casing A and fine B, and is firmly secured thereto.

The portion of the casing A above the diaphragm J forms the chamber L,which is in communication with the portion of the interior of the casingor chamber M below said diaphragm and at rear with the exit flue H.

The operation is as follows:Air is admitted into the flue B from thebottom thereof, and gas admitted to the burner F. The gas is ignited,and the products of combustion rise in the chamber M of the casing A andheat the same and the flue B, whereby the air in the latter is highlyheated and discharged insaid condition into the apartment, the latterbeing heated also by the heat radiated from said casing. The products ofcombustion instead of being discharged directly into the exit flue H, isdeflected by the diaphragm J to the front of the chamber M, from whencethey are directed through the passage K to the chamber L, and thentraverse the latter rearward to the exit flue H, by which provision theproducts of the combustion have a circuitous course from the burner F tothe front of the casing, and then to the rear thereof, and thus there isan increased heating action of said products, both on the flue B and thetop and side walls of the chamber L, so that said products are utilizedto an increased extent, and the stove is rendered most effective inproducing heat, both from the casing A and the flue B. The perforatedplate E rests on the spider or open frame N and is contained within theperipheral flange P thereon, said flange engaging the inner face of thelower end of the casing A. In the center of said spider is a collar Q inwhich the lower end of the flue B is seated and in the center of the capplate or wall D is a collar R with which the upper end of the flue Bengages, said fine-thus being firmly sustained at both ends. Bolts Spass through the spider N, plate E, and wall D and the body of thecasing, thus firmly connecting said parts. The base T of the easing isadapted to have the legs U of the stove connected therewith in anysuitable manner.

While I have specified certain means for carrying out my improvements, Ido not wish to be limited exactly to the same, but desire to make suchchanges as may come within the scope of the novelty involved.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a. gas stove, a casing having a base ortion le s secured to. saidbasev ortion an open frame having a peripheral 'flang'e engaging theinner face of the lower end ofi. said casing above the base and acentral collar, a perforated plateresting uponthe horis zontal portionsof said peripheral flange and" collar within'said open frame, a fluehaving" its lower end received within said collar,

a supply pipe beneath said base and having. an upwardly extended portionreceived within the lower end of said flue, a closure for the upper endof the casing, an outlet therefrom a horizontallydisposed diaphragmbelow said outlet through which said supply tubeextends said diaphragmhaving a segmentali opening at the front of the stove and aburnerwithin. saidcasing above said perforated plate and surrounding the lowerend of said flue.

2. In a gas stove, a casing, an open frame, the base of the casingsustaining'said frame,- said frame having a collar centrally thereon anda flange on the periphery thereof,.a gas: burner in said casing, aperforated; plate which is rested on said open frame withinsaid flange,an air flue of tapered form with its larger end uppermost, saidfluebeing held frictionally in the plates at top and bottom, the lowerof whiclrlatter is. seated in said collar, an exit fiueon said casing-,aplate closing'the top of said casing, said diaphragm within said, casingsnugly embracing said airline below'said exit flue, the sam e.,;having apassage therein substantially opposite to said exit flue, and means forfastening said frame and plate to thecasing.

3. In a gas stove, a casing, an open frame, the base -of'the casingsustaining said frame, said'frame having a collar centrally thereon,

burner in said casing, a perforated plate which is supported on saidopen frame within saidflange, an air-tight flue extending entirelythrough said casingfrom topto bottom and-tapered inwardlyfrom its upperto its lower end, the lower end of saidtlue beingseated in said collarand frictionally held, an exit flue on said casing, a plate closingthetop of the-casing, said-plate having centrally thereon a collar in whichthe upper end of said flue isfrictionally and Wedgingly contained,aninlet flue having a vertical portion received in the lower end ofsaidair-tight flue, a diaphragmwithin said casinglbelow the'exit flueand having a passage'therein on the side of the air flue oppoe site saidexit, and means for securing the parts together.
